Assessing the effects of climate change on distributions of Cape Floristic Region amphibians
(Academy of Science of South Africa, 2015)
Climatic changes have had profound impacts on species distributions throughout time. In response, species have shifted ranges, adapted genetically and behaviourally or become extinct. Using species distribution models, ...
Convergent evolution associated with habitat decouples phenotype from phylogeny in a clade of lizards
(Public Library of Science, 2012-12-12)
Convergent evolution can explain similarity in morphology between species, due to selection on a fitness-enhancing phenotype in response to local environmental conditions. As selective pressures on body morphology may be ...
Counting chirps : acoustic monitoring of cryptic frogs
This study explores the utility of monitoring using acoustic spatially explicit capture– recapture (aSCR) with time of arrival (ToA) and signal strength (SS) as a quantitative monitoring technique to measure call density ...
How repeatable is the Environmental Impact Classification of Alien Taxa (EICAT)? Comparing independent global impact assessments of amphibians
(Wiley Open Access, 2017-03)
The magnitude of impacts some alien species cause to native environments makes them targets for regulation and management. However, which species to target is not always clear, and comparisons of a wide variety of impacts ...
Distribution and establishment of the alien Australian redclaw crayfish, Cherax quadricarinatus, in South Africa and Swaziland
Background The Australian redclaw crayfish (Cherax quadricarinatus, von Martens), is native to Australasia, but has been widely translocated around the world due to aquaculture and aquarium trade. Mostly as a result of ...
